UPIQ: Unified Photometric Image Quality dataset

Unified Photometric Image Quality dataset (UPIQ) UPIQ dataset is intended for training and evaluation of full-reference HDR image quality metrics. The dataset contains 84 reference images and 4159 distorted images from four datasets, TID2013 [1] (SDR), LIVE [2] (SDR), Narwaria et al. [3] (HDR) and Korshunov et al. [4] (HDR). Quality scores were obtained by re-aligning existing datasets to a common unified quality scale. This was achieved by collecting additional cross-dataset quality comparisons and re-scaling existing data with a psychometric scaling method. Images in the dataset are represented in absolute photometric and colorimetric units, corresponding to light emitted from a display.
